Merlin is a musical based on a concept by popular illusionist Doug Henning and Barbara De Angelis, written by Richard Levinson and William Link, with music (and incidental music) written by Elmer Bernstein and lyrics by Don Black. Production history Merlin opened on Broadway at the Mark Hellinger Theatre on February 13, 1983 and closed on August 7, 1983 after 199 performances and 69 previews. It was directed by Ivan Reitman and choreographed by Christopher Chadman and Billy Wilson. The cast included Henning as Merlin, Chita Rivera as an evil sorceress and, in supporting roles, newcomer Nathan Lane and a young Christian Slater. The show was not a critical or financial success, failing to recoup its estimated production budget of $4–6 million. It is remembered today chiefly because of the number of "preview" performances it played: while most shows play a month or so prior to inviting critics and having an official opening, Merlin had 69, never inviting the critics and postponing the opening three times, despite charging full ticket prices. During the musical's troubled previews, the original director (Frank Dunlop) was replaced by co-producer Reitman, while choreographer Billy Wilson was added to augment Chadman's work. At least four songs were cut during previews, including "These Are Not the Merriest of Days" which was replaced by "Put a Little Magic in Your Life". Synopsis The story focuses on the legendary wizard Merlin, not as an elderly man as he is usually depicted, but as a young apprentice still learning the rules of magic. Merlin must overcome the evil Queen and her attempts to install her son Fergus as the King of England over the rightful future King Arthur. During the production number "Put a Little Magic in Your Life", Henning mounted a white horse and rode it into a gigantic box, which was then closed and hoisted into the air above the stage. In midair, the box suddenly broke open, turning out to be empty. A moment later, Henning appeared at the opposite edge of the stage, still mounted on a horse. In another scene, Henning levitated and flew above the stage with no visible support. Anticipating the audience's suspicion that Henning was hanging on invisible wires, the set design for this scene included several large Stonehenge-like trilithons: Henning levitated beneath the lintels of these structures, which would have caught any wires hanging above him.
